149021-04-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 149021-04-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,9,0,2 and 1 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 149021-04:
(8*1)+(7*4)+(6*9)+(5*0)+(4*2)+(3*1)+(2*0)+(1*4)=105
105 % 10 = 5
So 149021-04-5 is a valid CAS Registry Number.

The sacrificial anode electrochemical technique, using an undivided cell and a constant current density, provides a nice preparative route for creating Si-Si and C-Si bonds without using alkali metals. Compared to the chemical organometallic synthesis, this method is extremely selective and can lead to original compounds not accessible by the chemical routes. Bases, such as the 2-pyrrolidone magnesium salt electrogenerated in the same conditions, allowed the stereoselective synthesis of Z-silyl enol ethers. Finally, the reduction potentials of a large number of chlorosilanes measured by cyclic voltammetry in standard conditions are reported.
